Can email take up to 2 hours to be delivered?

it can take a long time since it essentially sends it out one at a time via being uploaded from your computer each time...it also will depend on your speed, since most uploads are slow, it will take longer with larger emails even with small attachments your speed may not be able to handle it all...on top of that...it also will vary depending on your EMAIL servers if they are experiencing any problems, so check every few hours to see if it went through and also double check to make sure everything was typed correctly...even 1 mistake can make the difference between sending 50 emails vs 500 emails...
